[Purpose] The present study examined the effects of treatment using extracorporeal shock wave therapy (ESWT) on the muscle weight and function of the hind limb in sciatic nerve injury. [Subjects] Forty rats with sciatic nerve crushing injury were randomly divided into two groups: an ESWT group (n=20), and a control group (n=20). [Methods] The ESWT group received extracorporeal shock wave treatment, and the control group did not receive any treatment after injury. Experimental animals were measured for muscle weight on an electronic scale and were tested for function on a sciatic functional index (SFI). [Results] All groups showed significant increases in the weights of the left soleus and gastrocnemius muscles, and decreases in the weights of the right soleus and gastrocnemius muscles (p<0.05). Comparison of SFI scores and muscle weights between the groups showed significant differences in SFI scores, and the right soleus and gastrocnemius muscles (p<0.05) [Conclusion] Exercise programs that use ESWT can be said to be effective at improving the function of the sciatic nerve and preventing the denervation atrophy.
[目的] 本研究探讨体外冲击波疗法（ESWT）对坐骨神经损伤后后肢肌肉重量及功能的影响。[对象] 40只坐骨神经挤压伤大鼠随机分为两组：ESWT组（n = 20）和对照组（n = 20）。[方法] ESWT组接受体外冲击波治疗，对照组损伤后未接受任何治疗。用电子秤测量实验动物的肌肉重量，并通过坐骨神经功能指数（SFI）测试其功能。[结果] 所有组左比目鱼肌和腓肠肌重量均显著增加，右比目鱼肌和腓肠肌重量均降低（p < 0.05）。组间SFI评分和肌肉重量比较显示，SFI评分以及右比目鱼肌和腓肠肌存在显著差异（p < 0.05）。[结论] 采用ESWT的运动方案可有效改善坐骨神经功能并预防失神经萎缩。
